The plpevtch driver is an eventdevice driver for touchscreens under Xorg 7.x.

Why another touchscreen driver when evtouch already exists? I was using evtouchon my Flybook with Xorg 6.9 very long. But with Xorg 7.3 it was not working for me. ShortlyI bought a touchscreen and I was not able to get it to work with evtouch. Then quickly Icreated this new driver and it works in the way I want. plpevtch is not a fork of evtouch.

Supported Hardware

I have only 2 different touchscreens, so i can only say that it works for those. Butthe driver should work with any other eventdev touchscreen kernel driver too.

The driver was successful tested on

USB Touchscreen eGalax (ID 0eef:0001 D-WAV Scientific Co., Ltd eGalax TouchScreen)
Flybook Touchscreen PenmountLPC

Configuration

Important: its required that the evdev kernel module is loaded or builtin in your kernel!

Unity Touchscreen Input

Here is a sample configuration for Xorg 7.x xorg.conf

add to the ServerLayout

How to calibrate

add Option ‘Calibrate’ to the touchscreen section
restart the X server
move along the borders of your touchscreen multiple times (ignore the mouse pointer). Its required to get the minimum and maximum values of your screen.
search /var/log/Xorg.0.log for the last ‘plpevdev’ and ‘Calibrate’. You will see something like
(II) touchscreen: Calibrate | MinX: 67 | MaxX: 1984 | MinY: 42 | MaxY: 1920
use this values in the touchscreen section of your xorg.conf
remove the Calibrate Option in the touchscreen section
restart the X server

./configure — prefix=/usr/X11R7 && make && make install
